Description: Most motion-based tracking algorithms assume that objects undergo rigid motion, which is most likely disobeyed in real world. In this paper, we present a novel motion-based tracking framework which makes no such assumptions. Object is represented by a set of local invariant features, whose motions are observed by a feature correspon-
dence process. A generative model is proposed to depict
the relationship between local feature motions and object
global motion, whose parameters are learned efciently by
an on-line EM algorithm. And the object global motion is estimated in term of maximum likelihood of observations.Then an updating mechanism is employed to adapt object representation. Experiments show that our framework is
exible and robust in dealing with appearance changes,background clutter, illumination changes and occlusion Platform: |

Description: Detecting, identifying, and recognizing salient regions or feature points
in images is a very important and fundamental problem to the computer vision
and robotics community. Tasks like landmark detection and visual odometry,
but also object recognition benefit from stable and repeatable salient features
that are invariant to a variety of effects like rotation, scale changes, view point
changes, noise, or change in illumination conditions. Recently, two promising new
approaches, SIFT and SURF, have been published. In this paper we compare and
evaluate how well different available implementations of SIFT and SURF perform
in terms of invariancy and runtime efficiency. Platform: |

Description: For this project, the shadow removal method used by Finlayson et al. in [1] was implemented.
This report contains an overview of the mathematical background and a detailed
discussion on the experiments performed with the implementation.
This method consists of two independent steps. First, an illumination invariant image
is derived from a color image for which an appropriate color calibration is known. Second,
shadow edges are detected by finding edges in the intensity image that are not in the illumination
invariant image. Gradient information is then erased at those shadow edges, and
a new shadowless color image is formed by solving a Poisson’s equation. Platform: |
